1IMPROVEMENT IN GALVANIC BATHS FO-R TREATING DISEASES.

Specification forming part of Letters Patent No. 125,567', dated April9, 1872.

Specication describing certain Improvements in Galvanic Bath forTreating Diseases, invented by JOHN B. HATTING, ot' New York, in theState of New York.

. This invention consists in the arrangement of a metal bath-tub, partlyinsulated, and connected with one pole of a battery, in combination witha metal plate or plates suspended and immersed into the water of thebath-tub, but insulated from the bath-tub and connected with the otherpole of the battery to cause the current of electricity to pass directthrough the body of the patient operated upon.

In the accompanying drawing, Figure I represents a top view of theapparatus embodybodying my invention. Fig. II is a longitudinal sectionof the same, and Fig. III is a crosssection.

A represents a metal bathtub, painted on the inside at both sides up tothe lines a afor the purpose of insulating that part, leaving only themetal between the lines a a or in the central part of the bath-tubexposed. To this exposed part a wire, G, is attached, connected with onepole of a battery. Upon the top of the bath-tub a wooden frame, B, isarranged, upon which a wire, O, is fastened perfectly in sulated fromthe tub by means of this wooden frame B. This wire C is connected,through the wire D, with the other pole of the battery.

To the wire C, extending some distance on each side of the bath-tub,wires a and m are attached, projecting downward into the bathtub, andsupporting a metal plate, E.

The patient being placed into the bath-tub filled with any desiredmineral water, the plate E is placed into tub connected with the wiresO, when the apparatus is ready for operation.

Care must be taken that the metal plate E is wholly immersed iu thewater, and `that the plate does not come in contact with the patient.The current of electricity will then pass either through the wires C,plate E, the body of the patient, and outl through the uninsulated partof the bathtub between the lines a a, upon which the patient rests, andthe wire G, back to the other end or pole of the battery; or the currentof electricity may be made to pass in the contrary direction byconnecting the wires D and Gwith the opposite poles ot' the battery.

Instead of using a metal bathtub and insulating the same, as abovedescribed, so as to leave only the central part exposed, a bathtub ofany non-conducting material may be used, and a metal plate arranged inthe central part of the same extending the whole length of the bath-tuband both ends, and connecting this plate with one pole of the battery.

`What I claim as my invention, and desire to secure by Letters Patent,is'- A metal bath-tub, A, having bot-h sides perfectly insulated,leaving only the central part of the metal tub exposed, or itsequivalent, and connected with one pole of a battery, in combinationwith a metal plate, E, suspended in the water of the bath-tub, andconnected, through suitable wires m, a, O, and D, with the other pole ofthe battery, said plate E and wires m, a, and C being perfectlyinsulated from the bathtub A by means of a wooden frame B, substantiallyas and for the purpose hercinbefore set forth.
